Application filed August 3, 1907. Serial No. 386,857.

To all whom itmay concern:

. Be-it known that I, \I'IERBERT C. SOULE, a

citizen of the United States, and a resident of Wilkinshurg, inthetcounty of Allegheny and State. of Pennsylvania, have invented a newand useful Improvement in Electrical Apparatus, of which the followingis a specitica- 3 irlOIL' My invention relates to electrical apparatusand it has special reference to alternating current transformers whichare adapted to lie-suspended under thehodies of electric railwayvehicles.

The object of my invention is to provide 1-5 means" for supportin andinsulating the transformer leads am a readily removahle means forprotecting the transformer core and'windings.

Electric vehicles which are supplied with alternating current energy areusuallyequipped with transformers which serve to reduce theelectromotive' force of the line heforc it is applied to the vehiclemotors. According to my present invention, 1 provide a transformer ofthe aforesaid class which may he readily suspended from the body frameof an electric vehicle and one ,whichis specially protected from injury.

l i ure 1, of the accompanying drawings, is a ongitudinal elevation, andPig. 2 is an end elevation of a transformer constructed in accordancewith my invention, the inclosing casing being shown in section todisclose the I core and windings. Referring to the drawings, thetransformer here illustrated comprisesa laminated Inagnetizable coreinemher 1, awindin 2 rimary and secondary leads 3 and 4, and aninclosing easing 5 ada )ted to contain oil' or other insulating ijluitf.The magnetizahle core member is rovided with end frames 6 that areclamped together by bolts? The 1 extremities of the coils, of whichthewinding 2 is composed, are braced by coil supports 8. The supports 8constitute the subject-matter of, Patent No. 885,800, granted April 28,1908, to WestinghouseElectric & Manufacturi-ng Company, upon anapplication filed by V me, and comprise a pair of opposite side onstrips 9 and clamping rods or be ts 10.

".lhe transformer and a cover late 11 are secured to channel beams 12 tow rich the end frames 6 are bolted, the channel beams 12 being suspendedby suitable strips 13 from a beam 14 which forms part of the body frame5 of an electric car or other vehicle.

Any suitl ahle means may, of course, be employed for l supporting thechannel beams from the hody.

The high-voltage leads 3 are connected to one end of this transformer;winding 2 and extend through insulating bushings 15 and 16 that aresupported by] a-ilangcd cup 17 litted into a suitable ope ,ing in thecover plate '11. The hushing'ldprojects through the bottom of the cup17-, and the bushing 16 projects from onset its side walls at a pointoutside the transformer easing.

Thelow-voltage leads 4 also,c xtcnd through aninsulatingloushing18,corresponding to the bushing 15 and supported by a cup 15) which isfitted into a suitable opening inthc cover plate 11. After the leads arein position, the cups 17 and 10 are partially lillod with a liquidinsulating compound, which becomes SOlld at ordinary temperatures andserves to seal the openings around the leads and around the bushings. Aplate 13 of hard into the cup l9on top of the first layer of insulatingcompound and is provided with holes 1S through which the leads arethreaded. The cup is then provided with another layer of insulatingcompound. 'lhe stili' fiher washer prevents any movement of the from thecompound in case the latter were softened -hy high temperatures and, inthis way, the inner layer of the compound is ahlo to more effectuallyand iwrmanently seal the leads into the bushings through which theyextend.

plate ll'hy a plurality of holts 20 amhits outer surface is'providedwith ribs or corrugations 21 in order to improve its heatradiatingproperties.

It will, of course, be understood that the method of securing the coverplate 11 to an overhead wall or structure may he varied materiallywithout departing from the spirit of my invention and will be dependentupon existing conditions. It is conceivable that various othcrmodifications in the size and the arrangement or details may he effectedwithin the scope of my invention.

1 claim as my invention A 1. In a transformer, the combination with amagnetiual le core member, a winding and means for suspending the coremember leads which would tend to separate them The casing 5 isadiustahly secured to the insulating material, such as lilf er, .littedfrom an overhead support, of a removable cover plate and beams fromwhich the core i member is suspended and to Wlnch the cover plate isattached, of insulating bushings secured to the plate through which thetransformer leads extend, and a casing, for the transformer removablyattached to the E sulatron to seal the leads, and hard insulating coverplate.

3. In a transformer, the combination with a magnet-izable core memberand a winding, cross beams from which the core member is through whichthe transformer leads extend,

of an inclosing casing for the transformer removably secured to thecover plate and having a ribbed or corrugated external surface.

4. In a transformer, the combination with a magn'etizable core memberand a winding, cross beams from which the core member is suspended, acover plate attached thereto, llanged cups secured to the supportingplate and insulating bushingsseated in openings in the bottoms of thecups through which the transformer leads extend, of aninclosing casingfor the transformer removabl attached to the cover plate and having aribbed or corrugated external surface.

5. In a transformer, with a magnetizable core member and a winding,cross beams from which the core member is suspended, a cover plateattached the combination secured to the plate, of means for insularmgthe transformer leads from the cups o' sleeves and securing themthereto, id an inclosing casing for the transfrunuwr r;- movably securedto the cover plate ar hm ing a ribbed or corrugated external url'iu-e.

6. The eom inatirm with a bushing for electric leads and a cup'in whichthe lt-ushine' .1

is disposed, of alternate layers of molded invvashers to hold themlirrnl in position.

7. The coinZ-ination with a finishing; for electric leads, and a llaugedcup in which the l ushing is supported, of a stiffening and supportingpiate through whieh the leads are threznled, and a molded or east insulti com ound disposed in the cup on. be: of t 1e plate for the purpose ofsealin leads in place. i

8; The combination with a supprn'ting structure, of a transformer and acover plate. that are secured direetl to the surpportiug structure, anda casing for-the transformer removably attached to the cover plate.

9. The combination with a suppmti structure, of a transformer und aeasingg therefor that are independently suspended from the supportingstructure.
